Science Olympiad tournaments are rigorous academic interscholastic competitions that consist of a series of team events, which students prepare for during the year. These challenging and motivational events are well balanced between the various science disciplines of biology, earth science, chemistry, physics and technology. There is also a balance between events requiring knowledge of science concepts, process skills and science applications. In addition, during the day there are open house activities that consist of science and mathematics demonstrations, activities and career counseling sessions conducted by professors and scientists at the host institution occurring concurrently with the events.
